Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medicines, and in particular relates to a compound preparation consisting of vonoprazan and its soluble salt, amoxicillin and levornidazole or levornidazole phosphate and a preparation method thereof. Background Art
[0002] Helicobacter pylori (Hp) is a Gram-negative, microaerobic spiral bacterium that is closely related to human gastrointestinal diseases. Studies have shown that H. pylori infection can cause chronic gastritis and promote the occurrence and development of a variety of digestive tract diseases, such as indigestion, peptic ulcers and gastric cancer. Among them, the most serious consequence of H. pylori infection is the induction of gastric cancer. Studies have shown that 90% of gastric cancer cases worldwide are closely related to H. pylori infection. According to statistics from the World Health Organization, gastric cancer is the fourth most common cancer in the world and the second most deadly, causing nearly 750,000 deaths each year. Therefore, H. pylori infection seriously threatens human health and causes huge economic and social losses. The prevention and treatment of H. pylori infection has great applied research value.
[0003] The treatment of Helicobacter pylori is completely different from other microbial infections. Since it is extremely difficult to isolate and culture the bacteria, doctors mainly rely on clinical experience and statistical results of large health institutions (such as the World Health Organization) to develop anti-infection plans. At present, the World Health Organization recommends a triple therapy based on clarithromycin for the treatment of Helicobacter pylori infection: a proton pump inhibitor, clarithromycin, combined with amoxicillin or metronidazole or tinidazole for 14 days. However, the effectiveness of anti-Helicobacter pylori treatment has been declining in recent years, and the success rate of anti-Helicobacter pylori treatment in China has been less than 80%. The failure of anti-Helicobacter pylori infection treatment is mainly related to the increase in the bacteria's resistance to antibiotics. Studies have found that the resistance rate of Helicobacter pylori to clarithromycin, metronidazole and levofloxacin in people infected in Jiangsu and Zhejiang provinces in my country is 21.5%, 95.4% and 20.6%, and the proportion of resistance to three commonly used clinical antibiotics is as high as 7.6%. Due to the extensive resistance of Helicobacter pylori to antibiotics in my country, the existing treatment options cannot effectively control Helicobacter pylori infection in my country. Therefore, developing new drugs, preparations and materials to address the problem of multidrug-resistant Helicobacter pylori is of great significance to improving the health level of our nation.
[0004] Currently, proton pump inhibitors (PPIs) have been widely prescribed for the first-line treatment of acid-related diseases. However, PPIs do not always provide adequate efficacy, and the inhibitory effect on gastric acid secretion may vary from person to person. This is because CYP-2C19, a protein involved in PPI metabolism, has genetic polymorphisms in its encoding gene in different individuals. However, vonoprazan is not mainly metabolized by CYP2C19, and vonoprazan's inhibitory effect on the proton pump does not require acid activation. The drug enters the stomach at high concentrations and can produce the maximum inhibitory effect at the first dose, and this effect can last for 24 hours.
[0005] Vonoprazan Fumarate (TAK-38) was jointly developed by Takeda Pharmaceuticals and Otsuka Pharmaceuticals and was approved for marketing by the Pharmaceuticals and Medical Devices Agency (PMDA) of Japan on December 26, 2014. The specific structural formula is as follows:
[0006] Vonoprazan fumarate is a new type of potassium ion (K + Competitive acid blockers (P-CABs) can competitively inhibit K secretion in the final step of gastric acid secretion by gastric parietal cells. + With H + -K + -ATPase (proton pump) binding effect, resulting in a strong and lasting inhibition of gastric acid secretion. This drug is suitable for gastric ulcer, duodenal ulcer, reflux esophagitis, erosive esophagitis, gastroesophageal reflux disease, Helicobacter infection and peptic ulcer.
[0007] Currently, the combination packaged medicine of vonopion fumarate, amoxicillin capsules and metronidazole tablets (VONOPION®Pack) and the combination packaged medicine of vonopion fumarate, amoxicillin capsules and metronidazole tablets (VONOSAP® Pack 400&800) jointly developed by Takeda Pharmaceutical (Takeda) and Otsuka Pharmaceutical (Otsuka) for the treatment of Helicobacter pylori were approved for marketing by the Pharmaceuticals and Medical Devices Agency (PMDA) of Japan in June 2016.
[0008] Amoxicillin hydrate acts by inhibiting bacterial cell wall synthesis, while vonoprazan does not require acid activation and inhibits H in a reversible and potassium-competitive manner. + , K +-ATPase. Vonoprazan is strongly alkaline and stays in the acid-producing sites of gastric parietal cells for a long time, inhibiting the production of gastric acid. Vonoprazan does not show anti-Helicobacter pylori activity or Helicobacter pylori urease inhibitory activity. Metronidazole is reduced and converted into a nitroso compound (R-NO) through a reaction of the nitroreductase system in Helicobacter pylori. This R-NO shows a bactericidal effect against Helicobacter pylori. In addition, the hydroxyl radicals produced during the reaction will cleave DNA, resulting in an unstable DNA helical structure. The effect of vonoprazan in triple therapy with amoxicillin and metronidazole is believed to be to enhance the antibacterial activity of amoxicillin and metronidazole by increasing gastric pH.
[0009] The vonoprazan fumarate pharmaceutical composition currently on the market in Japan is used to treat Helicobacter pylori, and the three are taken separately. Patient compliance is poor and drug resistance is high. It is necessary to provide a new method to solve the above problems.
[0010] Therefore, we found in the study that the combination of levornidazole or levornidazole phosphate with vonoprazan fumarate and amoxicillin has a strong inhibitory effect on Helicobacter pylori strains and low drug resistance. It is a better drug combination for treating Helicobacter pylori infection. Summary of the invention
